SHA Hash Generator (SHA-1, SHA-256, SHA-384, SHA-512)
Generate SHA-1, SHA-256, SHA-384, or SHA-512 hashes of any text, entirely in your browser with the Web Crypto API. Nothing is uploaded.
What this hash generator does
Computes a SHA-1, SHA-256, SHA-384 or SHA-512 hash of your text using your browser's built-in Web Crypto API. The result is the hex digest — a fixed-length fingerprint of the input.
Why hashes are useful
Hashes fingerprint data: two inputs with the same hash are almost certainly identical, so hashes verify integrity and detect changes. SHA-256 and up are the secure choices; SHA-1 is kept for legacy compatibility and should not be used for security.
Frequently asked questions
What is a SHA hash?
A fixed-length fingerprint computed from your input. Any change to the input produces a completely different hash, so hashes are used to verify integrity and detect tampering.
Which algorithm should I use?
SHA-256 is the safe default. SHA-512 is stronger but slower. SHA-1 is only for legacy compatibility and should never be used for security.
Is hashing done locally?
Yes. Hashing runs entirely in your browser with the built-in Web Crypto API — your input never leaves this page.
Does SHA Hash Generator (SHA-1, SHA-256, SHA-384, SHA-512) upload my data?
No. SHA Hash Generator (SHA-1, SHA-256, SHA-384, SHA-512) runs entirely in your browser — your input never leaves this page.
Is SHA Hash Generator (SHA-1, SHA-256, SHA-384, SHA-512) free to use?
Yes. SHA Hash Generator (SHA-1, SHA-256, SHA-384, SHA-512) is completely free, with no account and nothing to sign up for.
